For each subsequence, we apply the bitwise XOR () operation on all the integers and record the resultant value. Since there are subsequences, this will result in numbers. Given array , find the XOR sum of every subsequence of and determine the frequency at which each number occurs.
We take all consecutive subsequences of integers from the array that satisfy the following: For example, if our subsequences will be: For each subsequence, we apply the bitwise XOR operation on all the integers and record the resultant value.
Jul 27, 2021 · In this HackerRank Xor sequence problem solution, we have given an array A and the left and right index L, R. we need to determine the XOR sum of the segment of A as A [L] XOR A [L + 1] XOR....A [R - 1] XOR A [R].
XOR represents binary addition without the "carry" for each digit. We want to see how many values of x that will give us n+x = n^x, which is when XOR is the same as ADDITION. This happens when there are no "carries".
The first line contains an integer , the number of questions. Each of the next lines contains two space-separated integers, and , the inclusive left and right indexes of the segment to query. On a new line for each test case, print the XOR-Sum of 's elements in the inclusive range between indices and .
